even this century scientists have been amazed by the fact that the quran contains depictions of the universe, sky, earth, stars, planets, the formation of night and day, the physical, mental and spiritual phases of the creation of human beings, explanations and descriptions related to plants, animals and insects, as well as comprehensive and clear explanations of everything that exists within the universe, such as clouds, rain, storms, mountains, trees, rivers and seas. when the quran was revealed, people did not possess such knowledge and for a long time they were unable to perceive the truth of these descriptions. however, as science developed throughout this and the last century, people have managed to understand the truths stated in the quran.
although fourteen centuries have passed since the revelation of the quran, no discrepancy, error or corruption has been observed in its doctrines, meanings or issues.
the quran constitutes a unity, not only in terms of diction, but also in terms of meaning and judgments. the words of human beings are not always the same in terms of elegance or accuracy. these words change in accordance with the mood of the writer or the speaker, or according to the conditions in which they occur. however, the diction and style of the quran has an unprecedented beauty and accuracy from beginning to end. although the meanings, judgments and messages of these words mention almost everything in the universe, from genesis to eternity, they show an absolute consistency, correctness and harmony. if one just finds these points and contemplates on them this is enough to understand that the quran is not a manmade book, but that it was sent by allah.
"do they not consider the quran (with care)? had it been from other than allah, they would surely have found therein much discrepancy." (an-nisaa, 82).
there are many  aspects  of  conciseness in the quran  and  they can be summarized  in general under  these  two  headings:
1.    the quran is addressed to all people: the fact that 1, 400 years ago the quran mentioned events that had not been heard of before, that these events occurred just as depicted in the quran, that it mentions ancient tribes, and that it presents a general but unique legal system which can be applied to all people in all places at all times is a miracle; remember that prophet muhammad was illiterate and could not read or write. it is known that prophet muhammad did not take any lessons from scholars or tutors and he did not study law or politics. in view of this, it would be impossible for such an illiterate person to have formed this unique legal system by himself; it is a system that has divine wisdom inherent in it and is presented in the most wonderful arabian rhetoric and coherence. thus, the conciseness and miraculousness of the holy quran is without a doubt.
2.    the conciseness of the quran is addressed to the arabs: the divine language of the quran is unique. the quran has a rhetoric and coherence which is attention-grabbing, mesmerizing and superior.
although the quran, which has a unique style and a wide and deep treasure of meaning, has been read repeatedly for centuries, the arab masters of rhetoric and coherence have not been able to write a similar text to date.
